In assembling light touch switch, attention should be paid to current detection. What are the specific problems? We will give you a detailed introduction in this respect.

After repeated use, the breadboard should be uncovered from the back, the springs with poor elasticity should be removed and adjusted with tweezers to enhance the elasticity so as to prolong the service life of bread wrench.
Current Detection of Light Touch Switches
The greatest advantage of using plug-in method to assemble circuit is that it is easy to change the circuit and components without welding and printed circuit board, and it can be used many times, easy to use and low cost.
Therefore, the light touch button switch has been widely used in product development, development process and curriculum design. However, the biggest disadvantage of the socket is that the spring of the socket will become loose and the elasticity will become worse after many times of use, which will easily lead to poor contact. It can only be used for testing, but can not enter the market as a product.
Therefore, the travel-time characteristic detection of high-voltage switch is an important content of high-voltage switch detection. Because the switching contact moves in a straight line, an attachment moving with the moving contact can be installed. When the moving contact is split and closed, the attachment moves in a straight line with the connecting rod. Through the photoelectric sensor, the continuously varying displacement can be transformed into a series of electric pulse signals.
It is also the basis for calculating the opening and closing speed of high voltage switch. In the control circuit of the current loop, the current amplifier usually chooses a larger gain. Its advantage is that a smaller resistance can be selected to obtain enough detection voltage, and the detection resistance has a smaller loss.
High-voltage switch opening and closing speed, especially the number of pulses, can realize the measurement of the whole travel parameters of the moving contacts. At the same time, the maximum speed and average speed of the moving contacts can be calculated by recording the time value of each electric pulse and dividing the displacement at the same time.
Waterproof light touch switch is a switch that can be washed in water or rain without failing. Generally, the level of waterproof switch is IP67, which means that it can completely protect the dust in the air. At the same time, it can be located at about 1M underwater, at room temperature, about 30 minutes or so without damage. Waterproof light touch switch is the speed of the moving contact before and after the switch closes and closes. Interruption performance has a crucial impact.
